Arkare WS2812B LED Strip Addressable RGB LED Pixels Light 3 3ft 144 LEDs Programmable Digital Dream Color Rainbow LED Ribbon Lights 5V Waterproof IP67 for Arduino Raspberry Pi No Power Controller

Technical Specs: IC type: WS2812B Light source: 5050 RGB LED LED Qty: 144 LEDs per meter (roll) 1 integrated RGB LEDs per segment, individually controllable R G B order: G/R/B; NOT R/G/B Wave length (NM): R,620~625nm ; G,515~525nm; B,465~475nm The gray level: 256 Color: 24-bit full color Beam angle:120° Voltage: DC 5V(do not exceed 6V DC) Max Current: 8.64A per meter (roll) Max Power: 43.2W per meter (roll) Protection level: Tube Waterproof IP67 Dimension: 14mm (0.55") wide, 4mm (0.16") thick with casing on, 6.9mm (0.27") long per segment, 1000mm (39.37”) long per roll. Connector: 3-pin JST SM PCB color: White Life span:?50000hrs Working environment: -20?to +50? Red wire~5V+; Black Wire~GDN; Green wire~Data Kindly Note Only 1x WS2812B LED strip in the package. To let it work, you need buy 5V power supply and WS2812B controller, which is not included. You must use a 5V DC power supply to power these strips, do not use higher than 6V or you can destroy the entire strip. If you connect more than two meters and set all the LEDs on full white, it will get orange/ red gradually. This is not quality issue but voltage drop. To solve this issue, you need to inject 5V power on both ends of the LED strip. The strips are made of flexible PCB. You can gently bend it to an arc. But please NEVER rudely bend it to right or acute angle, otherwise the circuit board will crack.
